Title: Lsi memory with self-correcting function
Inventor: TAKADA TADAHIDE
IPC: G11C29/42
Filed: 1988-05-16
Abstract: PURPOSE:To shorten a processing time by omitting a parity check when data are read and processing the reading of a memory cell, the writing of a data signal, the reading of a parity cell, the parity check, error correction and the reloading of parity cell information separately at the time of access and the time of reset when the data are written. CONSTITUTION:When the data are read, a time for the parity check processing, the error correction processing and the re-writing of correcting data can be omitted. When the data are written, the reading of a memory cell 1, which is a writing subject, the writing of the data signal, the reading of parity cells 2 and 3, the parity check processing, the error correction processing and the reloading operation of the parity cell information are executed separately at the time of the access and reset. Thus, the reading and writing operation can be executed at the high speed.

Title: Oscillation removing sonar device
Inventor: TANAKA ISOICHI
IPC: G01S7/56
Filed: 1982-07-12
Abstract: PURPOSE:To remove video oscillation due to a wave and to recognize an image of a school of fish clearly by limiting the output of an oscillation sensor, and making only an echo signal arriving from a slanting surface of a target into an image selectively. CONSTITUTION:The oscillation sensor 8 is installed to a location where it receives nearly the same oscillation condition with a transducer 1 to detect the extent of oscillation. The extent of oscillation is applied to a transmission and reception control circuit 7 and when the extent exceeds a predetermined value, control is carried out so that an echo signal applied from a receiving circuit to a main storage circuit 10 is canceled, or that the storage contents of the circuit 10 are not updated. Consequently, only echo signals less than specified oscillation are stored in the circuit 10 and applied to a modulating circuit 11. Thus, the output of the sensor 8 is limited to make only echo signals arriving from slanting surfaces of the target in the water into an image selectively, so an image 19 of a body such as a school of fish is recognized clearly.

Title: Method and device for washing and treating substrate
Inventor: TANAKA MASATO
IPC: C11D7/32
Filed: 1989-05-12
Abstract: PURPOSE:To improve the removal ratio of an impurity by inserting a choline washing treating process between a fluorine-content liquid treating process and a rinsing process in conventional washing treatment. CONSTITUTION:A natural oxide film on the surface of a wafer is removed by a surface treatment containing hydrogen fluoride, and the wafer is washed by a detergent including choline. The wafer is etched extremely thinly by the hydroxyl groups of choline at that time, and fluorine ions and impurities remaining on the surface of the wafer combine with the cations of choline and easily removable colloidal particles are formed (S11). The hydroxyl groups of choline bond with the surface of the wafer, H2O combines with the hydroxyl groups and a water molecular layer is formed (S2), and the surface of the wafer displays hydrophilic properties. Consequently, no droplet is shaped on the surface of the wafer in a rinsing process, and a surface layer section on which colloidal particles are attracted is flung away before in a spin-dry process S3 (S3). Accordingly, the impurities are removed approximately completely.

Title: Magnetron applied device
Inventor: HARADA AKIICHI
IPC: H01J23/36
Filed: 1992-05-13
Abstract: PURPOSE:To provide all the time stabilized operation even when microwave output is remarkably changed by boring a long slit in a waveguide of a micro wave circuit, and arranging an angle-shape vessel to form a means for absorbing variable quantity microwave electric power. CONSTITUTION:A long slit is bored in the tube axis direction at a central part of a waveguide 3 of a microwave circuit, and a flat angle-shape vessel made of an insulative material, in whose interior passage a liquid is flowing, is arranged in the waveguide 3 in such a manner that a plane thereof passes through the slit orthogonally to the waveguide 3 wall. In this case, the vessel is arranged to protrude in an angle-shape so that the protruding length inside the waveguide 3 can be adjusted, thus forming a means 9 for absorbing variable quantity microwave electric power. Even when microwave output is variously adjusted in accordance with an object of use of a load, since an operation condition of a magnetron itself is constant, the microwave output as well as oscillation frequency becomes constant, and the device can be used all the time in a desired oscillation state, i.e., in a state suitable for the load. A continuously stabilized operation state can be therefore obtained.
